Alu Alu Blister Foil Product Introduction:
Cold forming aluminum foil, the scientific name is cold stamping forming the solid medicinal composite rigid sheet (commonly known as cold forming aluminum, alu alu foil, cold form alu alu foil). Aluminum foil has a series of good properties, it is mainly used in three major fields such as medical packaging, electrical, and construction. Among them, the demand for packaging is the largest, and the packaging takes medicinal blister packaging as an example. Medicinal blister packaging is generally made of medicinal cold-formed composite alu household foil.

Cold Form Foil Processing Technology
A processing technology of cold form alualu foil(alu alu low heat foil), involving the production of cold-formed blister aluminum foil for aluminum composite or jumbo reels alu foil. First, composite glue is coated on the surface of OPA, and then enters the oven for treatment; the preheated aluminum foil and the coated nylon Hot-press compounding, mature semi-finished products are made by curing treatment; the semi-finished products are coated with compound glue again, enter the oven and compound with PVC materials, and then undergo curing treatment to form a finished product.
Cold Forming Alu Foil Production Standard:
It is made of environmentally friendly materials such as nylon (OPA) or polyester sheet (PET), aluminum foil(ALU), polyester sheet (PET), and imported glue, which are carefully developed, scientifically matched, and reasonable production technology. Because it uses all high-barrier materials, the permeability of water vapor and oxygen is almost zero. High barrier properties, safety, and non-toxic (no chlorine) are its biggest characteristics, which have a positive effect on the safety of medicines according to the guarantee.
Cold Forming Foil Characteristics
- Barrier property: alu alu cold forming foil (also known as alu-alu foil cold forming) is currently the best barrier performance of medicinal hard films, which can almost completely isolate water vapor, oxygen, ultraviolet rays, and have excellent fragrance retention performance.
- Advantages compared with traditional PVC: Each blister forms an independent unit that completely isolates water vapor, oxygen, and ultraviolet rays. Taking out part of the contents of a board of tablets has no effect on other well-packaged medicines in the same medicine board.
- Appearance: concise, elegant, and beautiful, it is the preferred way of packaging health care products and medicines.
- individual packaging: Each cold form blister forms an independent unit that completely isolates water vapor, oxygen, and ultraviolet rays, and part of the contents of a tablet is taken out, which has no effect on other well-packaged drugs in the same tablet.
Alu Alu Base Foil Purpose
- Can be used as medicine packaging in high and low-temperature environments.
- It is used for packaging in the pharmaceutical and food industries. It is a packaging material for products that have high barrier requirements for moisture, oxygen, light, and chemicals.
- It is suitable for woven fabric, capsules, ointments, and emulsions.
Alu Alu Bottom Foil Suitable Range:
-
- It is suitable for drugs with high barrier properties.
- It can be used for packaging medicines such as pills, tablets, powders, suppositories, capsules, and external applications.
- It is suitable for cold press forming aluminum and aluminum blister packaging machine.
